    • New Charge (in addition to standing Charges): The ALMA Board requests the ASAC to address the permanent charges as outlined in its Terms of Reference, as well as the following ad-hoc charge:
      • ASAC to study and define the relative priority for the Communities to have access to raw data.
      • ASAC Terms of Reference (ToR) permanent charges:
        • 2.2.1 The permanent charges are:
          • a) Assessment of the performance of ALMA scientific capabilities: The ASAC shall indicate what information is required from the Joint ALMA Observatory (JAO) to perform this assessment.
          • b) Assessment of the technical aspects of the ALMA system performance: The ASAC shall indicate what information is required from the JAO to perform this assessment.
          • c) Assessment of the science outcomes from ALMA: Statistics on publications, citations, press releases, web sites, etc. collected by the Executives shall be collated by the JAO, and analyzed by the ASAC.
          • d) Recommendation of ways to maximize ALMA's scientific impact: This includes review of the scientific effectiveness of the Proposal Review Process after each Proposal cycle.
          • e) Reporting on operational or scientific issues raised by the wider community as communicated by the three regional Science Advisory Committees (ANASAC, ESAC and EASAC).
          • f) Assessment of the scientific impacts of the ALMA Development Program, and particularly of new projects that are proposed.

  5. ALMA Development
    • Development update.
      • ALMA Development: A Science Sustainability Program update: NA Report for ASAC
      • Presentations made at URSI GASS Montreal.
      • New NA Project call closed 30 Jan 2017.
        • The Cycle 5 Fiscal Year (FY) 2018 ALMA Development Project program has reached the next stage of the award process. On the basis of reviews by a panel of experts and funding capacity, which was unfortunately limited, several projects were selected to advance for possible Cycle 5 funding in FY2018, pending approval by the ALMA Management Team, ALMA Director, and ALMA Board. Two North America Projects were selected for advancement.
          • A Significant Upgrade to the ALMA Correlator, Principal Investigator (PI) Rich Lacasse (NRAO), co-Investigators Escoffier, Greenberg, Saez, Ojeda, Baudry, Webber. An upgrade to the 64-antenna ALMA correlator is proposed which will: (a) increase the frequency resolution by a factor of eight, providing extended high resolution spectral grasp while providing the increased resolution needed for the lower frequency bands; (b) provide four-bit correlation, improving efficiency and achieving the same sensitivity as currently but in 30% less time; (c) double the processed bandwidth; and (d) provide higher time resolution. Auxiliary upgrades to the archive, receivers, and digital part of the system will also be needed to realize all of these. Together, these improvements make ALMA significantly more efficient at all bands.
          • Lacasse Correlator Upgrade presentation at URSI GASS
          • Prioritization of Correlator modes being incorporated into ALMA Correlator Upgrade: Staging of Science Capabilities
          • Current priority:
            • Increased sensitivity, decreased observing time. 4bit mode, may require higher data rates (but we have an unimplemented 4 bit mode now!).
            • Improved spectral grasp at high spectral resolution. Requires higher data rates, archive expansion.
            • Higher spectral resolution. Can require higher data rates, archive expansion.
            • Broader bandwidth, additional spectral grasp. Requires upgrades to receivers (some capacity now at B6, B9, B10). Requires upgrades to digital path.
            • Higher time resolution. May require higher data rates, archive expansion.
          • Enabling New Science with the ALMA Phasing System (APS) Phase 2, PI Lynn Matthews (MIT), co-Investigators Crew, Fish, Hecht. The objectives of the APP Phase 2 are to further improve APS operations and enable a significantly greater diversity of scientific capabilities with a phased ALMA. Major components of the proposed Phase 2 work include: (a) improving the management of baseband delays in the correlator to enhance sensitivity and simplify data analysis; (b) enabling spectral line Very Long Baseline Interferometry; (c) extending the frequency range where phasing is offered to encompass Bands 1-7; and other enhancements.
